PXIe-5665 Calibration Procedure
3.
Set the RF source 2 power to 0 dBm.
4.
Measure the
Channel B Power
using the appropriate calibration factor for the power sensor
frequency. Calculate the
RF Source Power Direct
using the following equation:
RF Source Power Direct
= -
Channel B Power
5.
Repeat steps 2 to 4 for all remaining frequencies in Table 2 or Table 3.
